BALL-COOK.

Specification of Letters Patent.

Application filed April 7,1908. Serial N0. 425,688

To all whom it may concern:

Be it known that we, OOURTLAND WHIT- FIELD WEAVER and PETER GRAY ANDERSON,

of the city of Toronto, in the county of York and Province of Ontario, Canada, have in vented certain new and useful Im rovements in Ball-Cocks; and we hereby eclare that the following is a full, clear, and exact description of the same.

This invention relates to a ball cock for automatically controlling a water inlet and it relates particularly to the peculiar construction and operation of the parts hereinafter set forth and pointed out in the claims. For an understanding of the invention reference is to be had to the following description and to the accompanying drawings in which Figure 1, is a vertical .section showing the osition ol' the parts when the tank is filled. ig. 2, is a similar view to Fig. 1, showing the position of the parts when the tank is emptk 1 e Like characters of reference refer toparts throughout the specification and drawings.

The tank 23 is sup lied through the inlet pipe 8 and emptied through the outlet'pipe 28. The inlet pipe 8 extends into the tank 23 and is fitted with a valve body 1. The valve body 1 has a waterway-7 formed by a wall 9 within the valve body 1, and an annular water chamber 10 surrounding the waterway 7 and forming a means of communication from the latter through the waterwayl 1 to the tank 23. The top surface of the wall 9 is finished to form a seat 9 for .the valve 4, which is-of a flexible character, and has its outer edge 3 clam ed between the top surface of the valve body 1 and the adjacent surface of the dome 2, so that it can move into and out of contact with the valve seat 9 to cutoff and open the communication between the waterway 7 and the water chamber 10. Fitted in the valve 4 is a plug 5, having a diminutive waterway 6 for the passage of water from the waterway 7 to the water chamber 25 in the dome 2. Within the dome 2 is a valve chamber 26 and leading from the water chamber 25 to thevalve chamber 26 is a waterway 13, and leading from the valve chamber 26 is a waterway 24 which discharges into the overflow pipe 29.

Contained in the valve chamber 26 is a plunger valve 15 arranged to engage the valve seat 16 surrounding the waterway 13 .way 11 into the tank 23.

and close the passage from the chamber 25 through the waterway 13 and valve chamber 26 to the waterway 24.

=Fulcrumed on a pin 19, supported by lugs 17 forming part of the dome 2, is a lever 18 the arms 20 and. 21 of which project on opposite sides of the fulcrum in 19. Fixed to the arm21 is a float 22. The arm 20 engages the plunger valve 15 and presses it into engagement with the valve seat surrounding the waterway 13 when the float 22 rises in the tank 23, .to the position shown in Fig. 1.-

As the float 22 falls in the tank, the arm 20 disengages the plunger valve 15. The water passes through the inlet pipe 8 to the water way 7 and a diminutive stream circulates through the waterway 6 into the chamber 25. When the water in the tank 23 is at the level shown in Fig. 1, the float positions the arm 20 to press the plunger valve 15 into engagement with the valve seat surroundin the waterwa 13 and shut off the passage om the cham er 25 to the waterway 24 so that the water. circulating from the waterway 7 through the waterway 6 to the chamber 25 can accumulate in the chamber 25 and press the valve 4 against the valve seat 9* and close the passage from the waterway 7 tothe water chamber 10. By raising the valve plug 27 from its seat in the outlet ipe 28 the water in the tank 23 can em ty t ough the outlet pipe. As the level oi the water falls in the tank 23 the float 22 and lever 18 move from the osition shown in Fig. 1, to that shown in .ig. 2, and when the leverandv float are in the position shown in Fig. 2, the plunger valve.15 is relieved of the pressure of the arin 20. The pressurepf the water in the chamber 25 then lifts the plunger valve 15 to 0 en the passage from the chamber 25 t rough the waterway 13 and valve chamsov her 26 to the waterway 24 so that the valve 4 will be relieved of the pressure of the water in the chamber 25. The pressure of the water in the inlet pipe 8 and waterway7 then moves the valve 4 from the position shown in Fig. 1, to that shown in Fig. 2, to open the passage from the Waterway 7 to the water chamber 10 so that the water can flow from the inlet pipe 8' through the water chamber 10 and waterplug 27 is restored to its seat in the outlet pipe 28 the water accumulates in the tank and raises the float from the position shown in Fig. 2, to that shown in Fig. 1. When the I05 When the valve float attains the position shown in Fig. 1, the lever arm 20 exerts a pressure on the plunger valve 15 and restores the plunger valve to the valve seat surroundin the waterway'13 and shuts oil the passage or the water from the chamber 25 to the overflow pipe 29 so that the water will accumulate in the chamber 25. The accumulation of the water in the chamber 25 exerts sufficient pressure on the valve 4 to restore the last mentloned valve to its valve seat 9 and close the passage from the waterway 7 throu h the water chamber 10 to the position shown in Fig. 1, under the ressure of the water in the chamber 25 w on the plunger valve 15. is in the position shown in %y means of this construction the'action' of the valve 4 is positive when moving from j and returning to has valve seat 9 The valve 4 is preferably made of rubber or other like material havin not only the pro perty of flexibility but a so of resiliency so that it can adapt itself to its valve seat 9 and establish a tight contact therewith when in the position shown in Fig. 1

Having thus fully described what we claim as new and desire to secure by Letters Patent is I 1.. In a ball cook, a valve body comprising a'pressure chamber, an inlet waterway within the valve body and opposed tothe pressure chamber, a water chamber surrounding the inlet waterway, an outlet waterway communicating with the water chamber, a flexible valve held by the valvebody, the central part of the valve normally engaging the inner end of the inlet waterway to separate the pressure chamber from the water chamber and control the flow from the inlet water-' way to the outlet .waterway, a diminutive our invention valve but not connected therewith, and the other end rovided with a float.
